Definitions

  • the invention relates to particular novel cationic meta-phenylenediamine compounds, a dye composition comprising the latter and also a dyeing process using these compounds.
  • oxidation bases such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds.
  • oxidation bases are colourless or weakly coloured compounds, which, when combined with oxidizing products, may give rise to coloured compounds via a process of oxidative condensation.
  • couplers or colour modifiers the latter being chosen especially from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as indole compounds.
  • the “permanent” colour obtained by means of these couplers and oxidation dyes must moreover satisfy a certain number of requirements. Thus, it should have no toxicological drawbacks, it should allow shades to be obtained in the desired intensity, and it should show good resistance to external agents such as light, bad weather, washing, permanent waving treatments, perspiration and rubbing.
  • the dyes should also allow grey hair to be covered and, finally, they should be as unselective as possible, i.e. they should produce the smallest possible differences in colour along a same keratin fibre, which in general is differently sensitized (i.e. damaged) between its tip and its root.
  • couplers of the meta-phenylenediamine type for dyeing keratin fibres, especially the hair.
  • substituted meta-phenylenediamine couplers are known. These couplers may have the drawbacks of resulting in colours that are not sufficiently intense or chromatic and/or that are too selective.
  • the aim of the present invention is to obtain a hair dye composition that has improved dyeing properties in terms of intensity or chromaticity and/or selectivity and/or resistance to external agents.
  • the Applicant has now found a new family of couplers composed of cationic meta-phenylenediamines. These couplers result in a wide range of colours in oxidation dyeing. They make it possible in particular to expand the colour range while improving the harmlessness of the couplers of the oxidation dye. Furthermore, these cationic meta-phenylenediamines make it possible to obtain colours having varied shades and that are powerful and chromatic.
  • One subject of the invention is therefore a meta-phenylenediamine compound having the following formula (I), the addition salts thereof and the solvates thereof:
  • Another subject of the invention is a composition for dyeing keratin fibres comprising, in a suitable dyeing medium, at least one meta-phenylenediamine compound having formula (I) as defined above.
  • Another subject of the invention is a process for dyeing keratin fibres consisting in applying this composition to said fibres.
  • composition of the present invention for dyeing keratin fibres, in particular human keratin fibres such as the hair.

  • a final subject of the invention is a dyeing kit comprising, on the one hand, a dye composition containing a compound having formula (I) and, on the other hand, a composition containing an oxidizing agent.
  • the compounds of the present invention make it possible in particular to obtain compositions for dyeing keratin fibres that are suitable for use in oxidation dyeing and that make it possible to obtain a hair colour that has improved dyeing properties in terms of intensity or chromaticity and/or selectivity and/or resistance to external agents such as shampoo, sweat, permanent reshaping and light.
  • One subject of the invention is therefore a meta-phenylenediamine compound having the following formula (I), the addition salts thereof and the solvates thereof:

Description

CROSS REFERENCE TO RELATED APPLICATIONS
This is a national stage application of PCT/EP2013/063389, filed internationally on Jun. 26, 2013, which claims priority to U.S. Provisional Application No. 61/695,316, filed on Aug. 31, 2012, as well as French Application No. 1256309, filed Jul. 2, 2012.
The invention relates to particular novel cationic meta-phenylenediamine compounds, a dye composition comprising the latter and also a dyeing process using these compounds.
It is known practice to dye keratin fibres and in particular human hair with dye compositions containing oxidation dye precursors, which are generally known as oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds. These oxidation bases are colourless or weakly coloured compounds, which, when combined with oxidizing products, may give rise to coloured compounds via a process of oxidative condensation.
It is also known that the shades obtained with these oxidation bases may be varied by combining them with couplers or colour modifiers, the latter being chosen especially from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as indole compounds.
The variety of molecules used as oxidation bases and couplers allows a wide range of colours to be obtained.
The “permanent” colour obtained by means of these couplers and oxidation dyes must moreover satisfy a certain number of requirements. Thus, it should have no toxicological drawbacks, it should allow shades to be obtained in the desired intensity, and it should show good resistance to external agents such as light, bad weather, washing, permanent waving treatments, perspiration and rubbing.
The dyes should also allow grey hair to be covered and, finally, they should be as unselective as possible, i.e. they should produce the smallest possible differences in colour along a same keratin fibre, which in general is differently sensitized (i.e. damaged) between its tip and its root.
It is already known practice to use couplers of the meta-phenylenediamine type for dyeing keratin fibres, especially the hair. For instance, from document FR 2362116, substituted meta-phenylenediamine couplers are known. These couplers may have the drawbacks of resulting in colours that are not sufficiently intense or chromatic and/or that are too selective.
The aim of the present invention is to obtain a hair dye composition that has improved dyeing properties in terms of intensity or chromaticity and/or selectivity and/or resistance to external agents.
Surprisingly and advantageously, the Applicant has now found a new family of couplers composed of cationic meta-phenylenediamines. These couplers result in a wide range of colours in oxidation dyeing. They make it possible in particular to expand the colour range while improving the harmlessness of the couplers of the oxidation dye. Furthermore, these cationic meta-phenylenediamines make it possible to obtain colours having varied shades and that are powerful and chromatic.
One subject of the invention is therefore a meta-phenylenediamine compound having the following formula (I), the addition salts thereof and the solvates thereof:
Figure US09345653-20160524-C00002
in which:
    • R represents a hydrogen or halogen atom; a C1-C4 alkyl group; a carboxyl group or a (C1-C4)alkoxycarbonyl group;
    • R1 represents a C1-C10 (hydroxy)alkyl group, optionally interrupted with one or more non-adjacent oxygen atoms or non-adjacent NR′ substituents, substituted by a cationic CAT group,
    • R2 represents a hydrogen atom or a C1-C4(hydroxy)alkyl group,
    • R1 and R2 may form, together with the atom that bears them, a cationic heterocycle with 5 to 8 members,
    • R′ represents a hydrogen atom or a C1-C4(hydroxy)alkyl group,
    • An− represents an anion or a mixture of anions which are organic or inorganic and cosmetically acceptable.
Another subject of the invention is a composition for dyeing keratin fibres comprising, in a suitable dyeing medium, at least one meta-phenylenediamine compound having formula (I) as defined above. Another subject of the invention is a process for dyeing keratin fibres consisting in applying this composition to said fibres.
Another subject of the invention is the use of the composition of the present invention for dyeing keratin fibres, in particular human keratin fibres such as the hair.
The invention also relates to multi-compartment devices comprising compositions containing one or more couplers chosen from the compound having formula (I) or an addition salt thereof with an acid.
A final subject of the invention is a dyeing kit comprising, on the one hand, a dye composition containing a compound having formula (I) and, on the other hand, a composition containing an oxidizing agent.
The compounds of the present invention make it possible in particular to obtain compositions for dyeing keratin fibres that are suitable for use in oxidation dyeing and that make it possible to obtain a hair colour that has improved dyeing properties in terms of intensity or chromaticity and/or selectivity and/or resistance to external agents such as shampoo, sweat, permanent reshaping and light.

    • an “alkyl group” is a straight or branched C1-C20 and preferably C1-C8 hydrocarbon-based group;
    • a “(hydroxy)alkyl” is an alkyl group optionally substituted by a at least a hydroxyl group
    • an “alkenylene group” is an unsaturated hydrocarbon-based divalent group as defined previously, which may contain from 1 to 4 conjugated or unconjugated —C═C— double bonds; the alkenylene group particularly contains 1 or 2 unsaturated groups;
    • the expression “optionally substituted” attributed to the alkyl group means that said alkyl group may be substituted by one or more groups chosen from the following groups: i) hydroxyl, ii) C1-C4 alkoxy, iii) acylamino, iv) amino optionally substituted by one or two identical or different C1-C4 alkyl groups, said alkyl groups possibly forming with the nitrogen atom that bears them a 5- to 7-membered heterocycle, optionally comprising another heteroatom identical to or different from nitrogen; v) or a quaternary ammonium substituent —N+R′R″R′″, M− for which R′, R″ and R′″, which may be identical or different, represent a hydrogen atom or a C1-C4 alkyl substituent, or else —N+R′R″R′″ forms a heteroaryl such as imidazolium optionally substituted by a C1-C4 alkyl substituent, and M− represents the counterion of the corresponding organic acid, inorganic acid or halide;
    • an “alkoxy group” is an alkyl-oxy group for which the alkyl group is a straight or branched C1-C16 and preferentially C1-C8 hydrocarbon-based group;
    • when the alkoxy substituent is optionally substituted, this implies that the alkyl group is optionally substituted as defined hereinabove;
    • the expression “at least one” is equivalent to “one or more”; and
    • the term “inclusive” for a range of concentrations means that the limits of that range are included in the defined range.
It should be noted that, in the text hereinbelow, unless otherwise indicated, the limits of a range of values are included in that range.

The dye composition in accordance with the invention may also contain one or more direct dyes that may in particular be chosen from nitrobenzene dyes, azo direct dyes and methine direct dyes. These direct dyes may be of nonionic, anionic or cationic nature.
The medium that is suitable for dyeing, also known as the dye support, generally comprises water or a mixture of water and one or more solvents, for instance C1-C4 lower alcohols such as ethanol and isopropanol, polyols such as propyleneglycol, dipropyleneglycol or glycerol, and polyol ethers such as dipropyleneglycol monomethylether.

Needless to say, a person skilled in the art will take care to select this or these optional additional compound(s) such that the advantageous properties intrinsically associated with the oxidation dye composition in accordance with the invention are not, or are not substantially, adversely affected by the envisaged addition(s).
The pH of the dye composition in accordance with the invention is generally between 3 and 12 approximately and preferably between 5 and 11 approximately.

The composition according to the invention may comprise one or more oxidizing agents.
The oxidizing agents are those conventionally used for the oxidation dyeing of keratin fibres, for instance hydrogen peroxide, urea peroxide, alkali metal bromates, persalts such as perborates and persulfates, peracids and oxidase enzymes, among which mention may be made of peroxidases, 2-electron oxidoreductases such as uricases, and 4-electron oxygenases, for instance laccases. Hydrogen peroxide is particularly preferred.
The dye composition with or without oxidizing agent according to the invention may be in various forms, such as in the form of liquids, creams or gels, or in any other form that is suitable for dyeing keratin fibres, and especially human hair.
It may result from the mixing, at the time of use, of several compositions.
In particular, it results from the mixing of at least two compositions, one comprising at least one compound having formula (I), optionally one or more oxidation bases, optionally one or more additional couplers other than the compounds having formula (I) or salts thereof, and a second composition comprising one or more oxidizing agents as described above.
The composition of the invention is thus applied to the hair for the dyeing of keratin fibres, either as is or in the presence of one or more oxidizing agents for the dyeing of keratin fibres.
The process of the present invention is a process in which the composition according to the present invention as defined previously is applied to the fibres, either alone or in the presence of an oxidizing agent, for a time that is sufficient to develop the desired colour. The colour may be developed at acidic, neutral or alkaline pH, and the oxidizing agent may be added to the composition of the invention just at the time of use, or it may be used starting from an oxidizing composition which comprises it and which is applied simultaneously with or sequentially to the composition of the invention.
In one particular embodiment, the composition is devoid of oxidizing agent and is mixed, preferably at the time of use, with a composition containing, in a medium appropriate for dyeing, one or more oxidizing agents, these oxidizing agents being present in an amount sufficient to develop a colour. The mixture obtained is then applied to the keratin fibres. After a leave-in time of approximately 3 to 50 minutes, preferably approximately 5 to 30 minutes, the keratin fibres are rinsed, washed with shampoo, rinsed again and then dried.
The oxidizing agents are those indicated above.
The oxidizing composition may also contain various adjuvants conventionally used in compositions for dyeing the hair and as defined above.
The pH of the oxidizing composition containing the oxidizing agent is such that, after mixing with the dye composition, the pH of the resulting composition applied to the keratin fibres preferably varies between 3 and 12 approximately and more preferably still between 5 and 11. It may be adjusted to the desired value by means of acidifying or basifying agents customarily used in the dyeing of keratin fibres and as defined above.
The ready-to-use composition which is ultimately applied to the keratin fibres may be in a variety of forms, such as in the form of liquids, creams or gels or any other form appropriate for carrying out dyeing of keratin fibres, and in particular of human hair.
Another subject of the invention is a dyeing “kit” or multi-compartment device in which a first compartment contains the dye composition devoid of oxidizing agent of the present invention defined above, comprising one or more oxidation bases chosen from the compound having formula (I) or the addition salts thereof with an acid, and a second compartment contains one or more oxidizing agents.

Figure US09345653-20160524-C00015
Figure US09345653-20160524-C00016
As an example, when R1 represents a C1-C10 alkyl group substituted by a cationic group, said alkyl group being interrupted with one or more heteroatoms chosen from NR2 or O, then the method of synthesis used may be one of the three following:
Figure US09345653-20160524-C00017

Figure US09345653-20160524-C00019
Figure US09345653-20160524-C00020
The substitution reaction is performed in a dipolar solvent such as acetonitrile, THF or in DMF or NMP, or in an alcohol such as ethanol for instance, in the presence of a base such as triethylamine, ethyldiisopropylamine, sodium hydroxide or potassium hydroxide, for instance, and one or more HOAZ1H equivalents for 1 to 24 hours at a temperature from 20° C. to the reflux temperature of the solvent.
The hydroxyl function thus introduced is then substituted by a halide (for instance mesyl or tosyl halide) in a solvent such as acetonitrile, THF or in an alcohol such as ethanol, for instance, in the presence of a base such as triethylamine, ethyldiisopropylamine, sodium hydroxide or potassium hydroxide, for instance, for 1 to 24 hours at a temperature from 20° C. to the reflux temperature of the solvent.
The substitution of the leaving group introduced in the preceding step is performed either by reaction with an aromatic tertiary amine such as methylimidazole to lead directly to the cationic compounds, or by reaction with a particular primary or secondary amine, for instance N,N-dimethylethylenediamine or 2-piperidin-1-ylethanamine to lead to the compounds that are alkylated with at least one equivalent of alkyl halide or methyl sulfate in a solvent such as THF or acetonitrile or dioxane or ethyl acetate for 15 minutes to 24 hours at a temperature ranging from 15° C. to the reflux temperature of the solvent, to give the cationic nitro compounds.
The nitro substituent of these compounds is reduced under standard conditions, for instance by performing a hydrogenation reaction under heterogeneous catalysis in the presence of Pd/C, Pd(II)/C, Ni/Ra, etc., or alternatively by performing a reduction reaction with a metal, for instance with zinc, iron, tin, etc. (see Advanced Organic Chemistry, 3rd Edition, J. March, 1985, Wiley Interscience and Reduction in Organic Chemistry, M. Hudlicky, 1983, Ellis Horwood Series Chemical Science).
The examples which follow serve to illustrate the invention without, however, exhibiting a limiting nature.
